all section of the forum can show every users trust level
This would be a bit too much. In some areas it would be counter productive.
For instance in politics or serious discussions. If the guy is painted red it could weaken his point, even if he is right.
I agree, politics or serious discussion shouldn't show trust. But any section where people can trade or give "advice" of any kind, trust should be displayed. I think it's important that users know if the person scammed someone before or not. Like Beginners and Help.
Someone is advertising a website for creation of vanity addresses and there were reports that BTC was stolen form such addresses.
And the local boards should make trust visible on every board, the scammers are not that dumb to know it and post the topic in a section where trust isn't visible, like Projektentwicklung (project development).
We have no Mod to move scam topics to an appropriate section, so the scammers can organize their shitshow pretty well. Of course, such topics are always selfmoderated.
Here is our famous scammer:

And in regards of getting a new moderator:
We really need a new Mod for things like that. I recommend Lafu but we still have a discussion if anyone else wants to become Moderator or Backup-Moderator to avoid situations like right now, when the German section is out of any Moderator.
